CHAPTER 2: Introduction
2. Introduction 2.1 Description The 10/100 to 100BASE-FX Media Converters connect your twisted-pair standard or Fast Ethernet to a multimode or single-mode Fast Ethernet fiberoptic network without adding to your repeater count. Featuring automatic MDI/MDI-X selection and Link Fault Setting (LFS), the media converter allows for direct connection to a workstation, switch, or hub. You can use either straight-through or crossover cable between RJ-45 ports. The converter also has a DIP switch for manually setting half- or full duplex mode configuration for the 100BASE-FX fiber port. Once the DIP switches are set, the system auto-reboots to new configurations without powering off. Additional features include: • Store and forward at full wire speed. • Compatible with other 10BASE-T and 100BASE-TX/-FX devices. 9

3. Installation 3.1 Things to Consider Before You Install the Converter 3.1.1 LOCATION The converter’s location may greatly affect its performance. When selecting a location, consider these guidelines: • Choose a fairly cool and dry spot. See Chapter 1 for the acceptable temperature and humidity operating ranges. • Select a location free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. • Leave at least 4 inches (10.2 cm) of space at the front and rear of the unit for ventilation.

CHAPTER 3: Installation
3.1.2 THE DIP SWITCHES The seven DIP switches are show in Figure 3-1. A description of each switch’s function in the chart below.
Figure 3-1. DIP switches. DIP Switch
1 2 3 4 5 6 7
Function
Enables/disables auto-negotiation (RJ-45) Copper port (RJ-45) duplex mode: full or half-duplex Copper port (RJ-45) data bit rate: 10 Mbps or 100 Mbps Fiber port duplex mode: full duplex or half duplex Enables/disables Link Fault Signaling (LFS) Enables/disables Local Loopback (LLB) Enables/disables Remote Loopback (RLB)
3.1.3 NWAY DIP-SWITCH SETTING Use the NWay DIP switch (#1) to activate NWay operations. The switch’s default setting is ON. Before connecting any network device, see if it supports NWay. If it does, double check that the converter’s NWay DIP switch is ON. The converter will automatically 13
10/100 TO 100BASE-FX MEDIA CONVERTERS
set the optimum speed and duplex mode on the copper segment. Skip the settings for DIP-switches 2 and 3 when NWay is activated. If your network device does not support NWay, set the NWay DIP switch (#1) to OFF. Then use DIP-switch 2 to manually select either half-duplex (HD) or full duplex (FD) mode. Use DIP-switch 3 to manually select either 10- or 100-Mbps speeds. Set the NWay switch OFF when connecting to an autosensing device that only supports 10/100-Mbps detection. Some earlier switch models support only autosensing of speed, not autodetection of speed and duplex mode (autonegotiation). IMPORTANT! In order to configure DIP-switches 2 (duplex mode) and 3 (speed), set DIP-switch 1 (NWay) OFF.
If you experience any of the problems listed below, make sure the NWay switch is properly set. 1. The LNK LED is not lit and the connection cannot be established. 2. The LNK LED is lit and the connection is fine, but the converter cannot transmit or receive data.
14
CHAPTER 3: Installation
3. The converter functions properly for awhile, but then it doesn’t work. It works after powering off and then on again. 3.1.4 LINK FAULT SIGNALING (LFS) LFS is extremely helpful in network status monitoring. The LFS LED will immediately light when a cable has been severed or when some other disruption in service occurs. The LFS function monitors both copper and fiber segments, giving a total connection status report. Set LFS (DIP-switch 5) to ON for normal operation. Set LFS to OFF when installing cables or when testing the network connection. NOTE The LFS feature influences both fiber and copper segments. Therefore, when disruption occurs on either segment, LFS will be activated and the LED will light, indicating that the entire connection is down. To take advantage of the full benefits of LFS, four converters can be used to build a primary and a secondary link. They must be connected to a switch that supports Spanning Tree or Fast Spanning Tree protocols. By default, transmission of data will travel via the primary link. Once a fault has been detected, transmission will automatically be switched to the secondary link, resulting in “non-stop” network connectivity.
15
10/100 TO 100BASE-FX MEDIA CONVERTERS
3.1.5 LOOPBACK TESTS The converter features DIP switches to activate both local and remote loopback diagnostic test functions. Use local loopback to see if the copper segment is connected properly. Use the remote loopback to see if the fiber segment is connected properly. See Figure 3-2. Converter B
Converter A Copper Local Loopback
Fiber Remote Loopback
Figure 3-2. Remote and local loopback tests.
Turning DIP-switch 6 ON enables local loopback. Turning DIP-switch 7 ON enables remote loopback. Make sure that the cables are connected properly before getting started. Conduct either the local or remote test, but not both at the same time. Follow the steps listed on the next few pages to perform the diagnostic tests.
